[quote=jsteele][quote=Anonymous][quote=jsteele][quote=Anonymous][quote=jsteele][quote=Anonymous]Jeff, which model of the i4 did you decide on and are you happy with the car?[/quote]

But, as I said initially, we have done five 1500 mile trips in it. [b]It is very comfortable on trips and we just have to accept that we will be taking a break every two hours or so.[/b] We haven't had a single problem with it and I highly recommend the car.

DP, but why the breaks so often? Uncomfortable? Or is that due to needing charging or something?[/quote]

Due to the need to charge. The car is very comfortable. The nature of EV batteries is that they charge the fastest at their lowest state of charge. Charging from 80% to 100% is very slow and may take as long as 10%-80%. Therefore, you normally only charge to 80% unless you have no choice.

What's the average charge time for say, 25% to 75%? Is that the 2 hour mentioned, or would that take longer than 2 hours on average?[/quote]

No, the two hours is roughly the time we drive between stops on long trips. Sometimes closer to 2 1/2 hours. Charging time is highly dependent on the car because some have much better charging. But, you can expect about 20 minutes for a 25% to 75% charge with most new cars. Some will be faster and some slower, but that is probably a good ballpark.

There are different strategies. My preference is to stay at least 30 minutes when we stop to charge and get as much of a charge during that time as we can. However, in most cars the charging curve is very high at a low state of charge and then starts to drop at some point, often near 50%. So some drivers like to run their batteries very low and then charge from say 5% to 50% and then get back on the road. They are only charging during the highest part of their charging curves and, therefore, spending less time charging. I will tend to do 20% - 80% charges. This is all on DC fast chargers, of course, which we only use during long trips. At home, everything is slower level 2 chargers which take hours.
